如何使用 jaxb 包装子列表
当尝试将客户>订单 1:n 关系与 jaxb 2.2.6 映射时,我希望将订单列表包装在单独的节点“订单”中。
目前结果是:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Customer>
<id>100</id>
<name>John Doe</name>
<orders>
<address>100 main street, smalltown, pa</address>
<orderid>1100</orderid>
</orders>
<orders>
<address>5 broadway, ny, ny</address>
<orderid>1200</orderid>
</orders>
</Customer>
但我想得到:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Customer>
<id>100</id>
<name>John Doe</name>
<orders>
<order>
<address>100 main street, smalltown, pa</address>
<orderid>1100</orderid>
</order>
<order>
<address>5 broadway, ny, ny</address>
<orderid>1200</orderid>
</order>
</orders>
</Customer>
需要更改哪些内容才能获得此结果?
相关源代码有:
- 客户界面
- 客户JaxbDao实施
- 订单界面
- OrderJaxbDao 实现
- TestCustomerWrite Junit4 Testcase
并使用以下 jaxb 实现:
